  • Beschreibung: Single event effects generated by ionizing radiation cause a variety of problems inside satellitesup to mission failures. In case of COTS-based nanosatellites, much effort has to be investedin mitigation measures and redundancy concepts. Increasingly, longer mission durations aretargeted for imaging instruments used as remote sensing devices, e.g., to observe long-termclimate processes. Highly integrated System-on-Module (SoM) architectures enable high processing performance for imaging applications with low resource requirements in terms of powerand mass. The major advantages of these architectures are flexibility, (re)programmability,modularity and module reuse. In order to achieve a fault tolerant design we modeled the radiation environment, estimating the hazards at module level with the objective to reduce therisks to an acceptable level by applying appropriate mitigation techniques. This approach results in an electronics design that combines hardware and software redundancies paired withreconfiguration strategies to assure system availability and reliability for mission lifetime longerthan 3 years in Low-Earth-Orbits (LEO). In this contribution, we will present a dual-imagerelectronics that uses an SRAM-based Xilinx Zynq-7000 architecture, which can accommodatea wide variety of imaging sensors in visible and near infrared spectral range and is part of alimb sounding spatial heterodyne interferometer to measure temperatures in the atmosphere.This instrument is scheduled for the Atmospheric Coupling and Dynamics Explorer (ARCADE)mission inside the International Satellite Program in Research and Education (INSPIRE) seriesof satellites.
